In primary succession, what grows on bare rock

Answer and Explanation:

During a primary succession, lichens grows on a bare rock at first. Lichen is a symbiotic relationship between fungi and algae. The fungi grows on the weaker parts of the rock (e.g. cracks) and derive nutrients. The availability of nutrients would allow algal species to perform photosynthesis and produce carbohydrates upon which fungi can survive. Fungi also help algae to anchor the rock material. The process usually occurs very slowly but, once the right conditions are established, mosses and grasses start appearing on the surface. To understand further this scheme, I have attached an image as well.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
